I have 77websites indexed for 7000 pages.
I was last week with 1.7phpdig and it works fine.
I've upgraded and...now : I can't find most of the webpages!
If I do a request with "allergie aux arachides" I have no result (it's one of the more important content of all the websites..

and phpdig suggest me : "acaricides allergi ###" which is slightly different but which find in his firts result the webpages I'm wanting...
Is there a problem of charset for such a confusion?
It is the same database, the same content_text and I don't remember any change from my own part.
So what? An idea?
